SC-1 Anchor Catcher

The SC-1 Anchor Catcher is a Retrievable Double Grip Tubing Anchor designed to anchor the Tubing String in tension or compression. When installed with the proper amount of tubing tension, this anchor prevents movement of the tubing String during rod pumping operations. This results in more oil production per pump stroke and in turn extends the life of the pump, rods and tubing decreases pumping costs.

Benefits

Prevents movement of tubing string during rod pumping operations

Allows higher production with each pump stroke

Extends life of the pump, rod and tubing

Decreases overall pumping costs

The SC-1 Anchor Catcher is a retrievable Double Grip Tubing Anchor designed to anchor the tubing string in tension or compression. When installed with the proper amount of tubing tension, this anchor prevents movement of the tubing string during rod pumping operations. This result in more oil production per pump stroke and in turn extends the life of the pump, rods and tubing decreases pumping costs.

The SC-1 Anchor Catcher incorporates an emergency shear release which is easily adjustable in the field. Unless otherwise specified, anchors are furnished with a total of 22,000 daN (50,000 lbs) secondary release shears.

The SC-1 Anchor utilizes drag block backed up by Inconel leaf springs which results in more positive drag, thus reducing repair costs by at least 50% of the cost for repairing older drag spring designs.

Operation

To Set

Install the Anchor Catcher in the tubing string just below or above the pump for the best results, although it may be installed at any point. Run to desired depth and rotate the tubing to the left to set the Anchor Catcher the number of turns required will depend on the casing weight. When the slips have set the tubing will torque up.

To ensure the anchor slips are solidly engaged with the casing, hold left hand torque on the tubing and set down 4,500-6,500 daN (10,000-14,500 lbs) of tubing weight. Pick up and set down several times to be sure the anchor slips are properly set in the casing. Pick up to install the dognut and land the tubing, making sure the tubing is in sufficient when landed.

To Release

To pull the SC-1 Anchor Catcher lower the tubing to release the tension, and rotate to the right while working the tubing up and down slightly. When pulling care should be taken to ensure the tubing is not rotated with left hand torque or it may cause the anchor to reset.

Should the Anchor Catcher fail to release with normal procedures, an upward pull of the tubing string weight, plus the total value of the shear pins will release the anchor.
